To all whom it may concern:

Be it known that I, EUGENE L. LAW, a citizen of the United, States, residing at Lubbock, in the county of Lubbock, and State of Texas, have invented certain new and useful Improvements in Water-Tank Cut-Offs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in.

devices for controlling the flow of water from elevated tanks or reservoirs.

In the drawings, Figure 1 is a side view of the important parts of the apparatus on a relatively large scale;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a vertical section of the parts adjacent to the upper end of the stand-pipe.

In the drawings, 1 indicates a tank or reservoir which is in an elevated position. It may be supported upon any suitable frame work or structure to hold it at the place desired.

2 indicates the stand-pipe or pipe through which the water is finally delivered at such point as may be selected below the tank.

This stand-pipe communicates with the in terior of the elevated tank by means of the following devices:

4 is a vertically arranged discharge pipe which passes into the tank and is carried down to any preferred point where the down flow of the water can be controlled. This discharge pipe is provided with threads at 14:, so that it can be tightly fastened and packed in the bottom wall 1 of the tank.

It is connected tothe stand-pipe 2 by means of a Y-coupler having an inclined leg 3 and a vertical leg 8. The inclined leg 3 is joined directly, or by means of elbows and joint pieces 7, to the stand-pipe. The supply pipe 1 is tightly fastened to the upper end of the Y coupler, and the lower end of the latter is closed by means of a plug 19 which has an angular head, and is joined by threads at 20 to the interior of the part 8. In the pipe plug 19 there is seated a plug 18 which carries the adjusting rod to be described.

At the upper end of the discharge pipe 4, within the tank, and at a short distance above its bottom, there is a cap or head 9. It is formed with a threaded seat by which it is secured to the threads at the upper end 1 Patented Dec. 1

of the discharge pipe, also with a val vejseat at 10 and a threaded seat at 22.

111's ahvalve which canbefitted tightly. to the seat 10 to stop the flow of water from the tank through the cap or head 9 into the discharge pipe. It is in the form of an ellip tical ball, and is made of rubber. The can rier for this valve is a vertically arranged tube indicated at 12. It passes through the valve ball 11, and is adjusted and clamped there by means of lock nuts 15 and 16 engaging with the threads at 13 on the valve carrier. This carrier tube extends down longitudinally through the discharge pipe 4, and into the Y 8. It is joined by a coupler at 30 with a vertical stem 17 which extends downward from the coupler to any suitable point where it is accessible for regulating the position of the valve, it having a hand wheel 29 at its lower end for this purpose. The valve stem is threadfitted into the plug 19 above described.

In the seat at 22, on the top of the cap or head 9, is fitted the threaded end of a vent tube 23. This is formed of one or more sections of piping sothat it shall be long enough to extend to points above the surface of the water in the tank 1. As shown, two sections are united by a coupler having a threaded tube at 24 and a smoothly bored tubular element 25. The latter part of the coupler serves as a guide for the upper part 26 of the tube or carrier for the valve or stopper 11. This part 26 being tubular, it has its upper end closed by a cap 27 to prevent the entrance of water. The upper end 28 of the vent tube 23 is open for the passage of air.

The mode of operation of the devices which I have described will be readily understood. The tank may be situated at any ordinary height, and the devices which provide enable me to quickly cut off or permit the flow of water at points close to the bottom of the tank, and at the same time allow all of the water to pass out of the down pipes, air entering to prevent the stoppage of down flow under vacuum.

What I claim is:

The herein-described device for controlling the flow of water from an elevated tank having in combination the stand pipe 2 for delivering the water at predetermined points near the ground, a discharge pipe extending through the bottom of the tank and communic'ating with the stand pipe; a cham bered cap 9 secured to the upper end of the discharge pipe and having: in its top a valve seat, a vent pipe secured to the said cap and communicating with the chamber therein, a

, longitudinally movable valve carrier 12 disposed fcentrally of the compressible valve andsecured adjustably thereto and extending continuously from points above the valve 16 to points relatively'near the ground, a slide guide for the valve carrier secured to the (topics of this patent may be obtained for ture, in presence of two witnesses.
